The Veris Industries CWLP Series is a line of CO2 sensors with embedded BACnet and Modbus communication protocols that give a more direct communication to the controller. These nondispersive infrared analyzers (NDIR) measure CO2 levels in ventilation systems and indoor living spaces. They connect to the facility’s automation system, alerting when CO2 levels are too high and triggering an inflow of fresh air to stabilize the environment. The sensors are configurable to multiple baud rates, and they can also act as humidity and temperature sensors. There is an adjustable setpoint relay, setpoint slider, and override button for local input.
